Sample rotary geometries

Friction welding can accommodate a wide variety of geometries as seen below. The process is best suited to a simple butt joint weld prep. The interface needs to be clean and, depending on accuracy/component requirements, can either be saw cut square to the axis within 1% or machined. The weld face of both parts needs to be clean and clear of any contaminants, in particular, rust, scale, oxides etc as this can jeopardise weld quality.

Small diameter components

Common applications include hand tool components, engine valves, bi-metallic pieces for electrical power distribution and power plant, pump shafts and plug valves in materials ranging from copper/aluminium and copper/steel to heat resistant stainless steels, nickel alloys and titanium. Other small diameter welded components include airbag inflators, turbo charger impellers, reamers and drills.
